Helicone

AI gateway and LLM observability for routing, debugging, and analyzing AI apps.

Helicone fits teams that need a practical gateway and observability layer for LLM requests, routing, rate limits, alerts, sessions, users, prompt improvement, datasets, and cost visibility across providers.

Qidao take

Helicone is strongest for LLM request logging. It is a weaker fit for offline evals alone.

Qidao fit index: 84/100

This is a Qidao method score for workflow fit, decision clarity, alternatives, risk, and practical use. It is not a user rating, paid placement, or benchmark claim.
